Take-Home Pay Calculator FAQ

What exactly gets deducted from my take-home pay?

Take-home pay is your salary after deducting National Pension, Health Insurance, Long-Term Care Insurance, Employment Insurance (the 4 major insurances), earned income tax, and local income tax.

How are the 4 major insurance premiums determined?

Each insurance has a set rate that's multiplied by your monthly pay (National Pension uses a standard monthly income amount, with a floor and ceiling). Rates are adjusted every year, so this calculator uses the 2026 rates.

Why might the income tax calculation differ from the actual amount?

This calculator's income tax is an approximation based on a simplified version of the National Tax Service's simplified withholding tax table. Actual withholding may vary based on individual factors like non-taxable items and dependent deductions, so it's best to check the exact amount on Hometax (the National Tax Service's online portal).

Are non-taxable items like meal allowances reflected?

This calculator treats the entire amount you enter as taxable. If your pay includes non-taxable items like a meal allowance (up to ₩200,000/month), your actual take-home pay may be a bit higher than this calculator's result.

Should I use annual salary mode or monthly pay mode?

If you know the amount on your monthly pay stub, use monthly pay mode. If you only know the total from your annual salary contract, use annual salary mode, which divides your entered annual salary evenly across 12 months.

This result is a reference calculation based on 2026 rates. National Pension, Health Insurance, Long-Term Care Insurance, and Employment Insurance are calculated using official rates, but income tax and local income tax are approximations based on a simplified version of the National Tax Service's withholding tax table, so they may differ from your actual withholding. For the exact tax amount, please check Hometax (National Tax Service).
